Your trying to make your DVD play a CDr instead of a DVDr? I'm not sure of the age of your player but chances are that it has dust on the lens. If you can, take out the screws of the unit and just remove the case, nothing else. Look for the lens which should be pointing up after the case is off and unit is facing you while on it's feet. Then take a Q-tip, a dry one and place on the top of the lens and turn it around at least 20 to 30 times from the outer edge to the middle with out putting any pressure on the lens. Be careful when taking the case off as a wire tap might be hooked up to the back of the front control buttons. You don't want to break this wire so be careful. If this doesn't work your player more than likely cannot play CDr's. I fixed my son's Sony playstation this way because the unit would not load the game. It's all dust that over time lands on the lens. Uriah
